Summary: Purchased this product for using with Smartphone. SmartPhone: Samsung Galaxy S Navigator: Google Navigation Connection: Bluetooth GPS Mouse from Argotronic - Android Market Place. Had Pharos bluetooth GPS.
Summary: Holds a charge forever. Grabs signal fast. Holds the signal when stuffed into a backpack or when it falls on the floor of the car and slides under the dash. How's it do that? The switch feels a little cheap, but it hasn't broken.
